Bad service Lenasia South

I have placed an online order at 1:50pm and only received my order an hour and 20 min later at 3:10pm. I then realized they had delivered Coke Zero instead of coke. I called at 3:13pm and they have advised that they will send someone with the correct item. I then called an hour and 10min after (4:33pm) to enquire about the cold drink and the lady had advised that the matter will be escalated to the manager. It is now 5:25pm and still nothing. Almost 4 hours later and still did not get my order corrected. So much for management assisting.
